| |
Hello,
We have a user that has reported an oops when removing the aoe module. This seems to have been happening since the 3.4 kernel, as you can see in this bug: https://bugzilla.redhat.com/show_bug.cgi?id=853064
The recreate steps and oops output from a 3.6.11 kernel is below. Any thoughts on what could be causing this?

I run the following commands sequentially
